Adjustment
In order to achieve optimal settings for economy
and comfort, we recommend adjusting the oper-
ating temperature of the c.h. water according to
the outside temperature, positioning the knob as
follows:
From 5 to 15 ûC

Your qualified installer will be able to recommend
the most suitable adjustment for your system.
The temperature and pressure gauge (4, Fig. 1.3
on page 2) will allow you to check that the set tem-
perature is obtained.

D.h.w. temperature

The temperature of the d.h.w. leaving the boiler
can be varied from a minimum of about 35°C to a
maximum of about 55°C (Fig. 2.8), by turning the
temperature control knob 9.

Adjustment of the d.h.w. temperature is complete-
ly separate from that of the c.h. circuit.
The adjustment system integrated within the
boiler automatically controls the flow of gas to the
burner in order to keep the temperature of d.h.w.
delivered constant, between the limits of maxi-
mum and minimum output.
Where the demand is at a low level or with the tem-
perature set to the minimum, it is normal to see a

Adjustment
It is advisable to adjust the d.h.w. temperature to

Moreover, where the amount of limescale present
in the water may be particularly great, not exceed-

ture control knob 9 corresponding to about 50°C
(Fig. 2.9), minimises annoying incidences of scale
deposits and clogging.
